This, invention ,rel ates to apparatus for marking or scoring surfaces by means of saws, and has particular reference to a simple and eific'ient" apparatus for scoring railway ties.

An object of the invention is to provide a sim le 'coniact "and efficient a aratus 17 i V 5 v i l l l from "the" detailed description given below taken in. connection with the accompanying drawings which form part of the specifications, and which illustrate one embodiment of the invention,:andfin which Fig; 1 -isfa' side elevation of the apparatus; Fig.2 is a plan view thereof;

"Fig; 3 a vertical transverse section taken on the line 3- 3 of'Fig. 2 looking in one direction; and g k p Fig;'4is a similarsectmn taken on the line 4 4 of Fig. 2 looking in the opposite direction. i

The preferred apparatus comprises a tram formed of U-shaped steelbeams 10, 11, 12 and 13", suppert'ecr above 'thetopsof wheels 14, 15, Mind 17 by means of bolster plates 18, 19, 20 and 21, mounted on wheel axles menu 23. I-beams' 24, and 26 extend across and rest onfbe'ams 12 and 13 and, with end beams 10 and 11', su'pport a top, surface or platform 27 orwotd. At one end of platform 27 channel beams 28 and 29 extend longitudinally thereof along opposite sidesbetween I-beams 24 and 25. Similarly at 'the'other end of platform 27 channel beams 30 and" 31 extend longitudinally"betweenI-b eams 25 and '26 The wheels 1417 inclusive, run on rails 32 and 33 support-ed on ties 34 with intervening tie plates 35. The top platform 27 is so arranged and constructed that its surface is at all points the same distance above the rails. 50 Rotary disk saws 36 and 37 are disposed on the outside of rails 32 and 33 and are supported on shaft 38 extending therebetween. The plane of the saws is parallel to the line of the rails 32 and 33. Near its ends, shaft 38 is journalled in blocks 39 and 40 slidable vertically between respective pairs of guide plates 41, 42 and 43,44, the upper ends of which are bolted to blocks 45 and 46 fastened to the under faces of channel beams 28 and 29.

As shown in Figs. 1 and 3, these guide plates 41, 42 and 43, 44 are provided with slots 47, 48, and 49, 50 in which the ends of bolts 51 and 52 mounted in blocks 39 and 4,

, ride. VNuts 53 and 54 are fastened to the threaded ends of bolts 51 and 52 and adjusting arms 55 and 56 fastened to their heads with intervening universal joints 57 and 58. These arms extend at an angle to one end of the truck and pass through openings in beams 11 and on their ends are provided with operating handles 59.

Connected to blocks 39 and 40 are vertical rods 60 and 61 extending upwardly therefrom g i channel beams 28 and 29 and having threaded ends engaged by threaded sleeves 62 and 63 provided with operating handles 64 and 65. The lower ends of these sleeves are adapted to rest on the top surface of platform 27 and determine the distance between the top of the platform and the bottom of saws 36 and 37. The saws are raised and lowered by cables 66 and 67 connected at one end to blocks 39 and 40, extending over pulleys 68 and 69mounted on platform 27 and connected at their other ends to hubs 70 and 71 on shaft 72 extending across the platform 27 and journalled in bearing plates 73 and 74 supporteclfrom beams 12 and. 13. Ahead wheel is mounted on shaft.72 to operate the same. A ratchet pinion 76 on shaft 72 is engaged by pawl 7'? on hearing plate 7 1 to hold the shaft in any desired position (see Figs. 1 and 4). Dogs 7 8 and 79 pivotally mounted on beams 28 and 29, can be swung to engage the threads on rods 60 and 61 to hold them in an elevated position.

A motor is housed in casing 81 on platform 27 and a belt on hub 83 of motor shaft extends to a hub 85 on saw shaft 38. Another belt 86 mtends from hub 87 on shaft 38 to hub 88 on another saw shaft 80. A idler pulley 90 on lever 91 pivoted to L-beam 92 on platform 27, engages belt 82 to lzeep 1t taut. This idler is adjusted by threaded rod 93 connected at one end to lever 91 and at the other end passing through a bracket plate 9 1 mounted on L-beam 92. This rod 93 is provided with a threaded sleeve 93'. An operating handle 95 is connected to sleeve 93. Scraper plates 96 bear on the top of wheels 1 l17 inclusive, and are supported by arms 97 pivoted to brackets 98 on the under side of beams 12 and 13.

Disposed on the inside of rails 32 and 33 near the other end of the truck are saws 99 and 100 mounted on shaft 89 supported in blocks 102 and 103 slidably between guide plates 104i, 105, and 106, 10?, the upper ends of which are bolted to blocks 108 and 109 fastened to the under faces of channel beams 30 and 81. These guide plates 104i, 105, and 106, 107 are provided with slots 110, 111. and 112, 113 in which bolts 114 and 115 on blocks 102 and 103 ride. Nuts 116 and 117 are on one end of bolts 114; and 115 and heads on the other ends are connected by universal joints 118 and 119 to adjusting arins 120 and 121, passing through openings in end beam 11 and provided with operatii handles 122 and Extending upwardly from blocks 102 and 103 are rods 12% and threaded at their upper ends to receive adjusting sleeves 120 and 127 provided with operatin handles 128 and 120. Cables 130 and 131 connected to blocks 1.02 and 103 exterd to hubs 13 1: and on shaft 7 2 above-mentioned. Idler pulley 136 engaging belt 86 is mounted on arm 137 pivotally connected to block 102 and at the other end to link 138 connected to rod 139 threaded. at its upper end and passing through platform A. threaded sleeve 141 on the end of rod 139 is provided. with an operating handle 142. Does 1 13 and 14:41 pivoted on channel beams 80 and 31 are adapted to be swung into engagement with the threads on rods 12L and 125 to hold them in their elevated positions.

In practical operation, the most frequent use of the apparatus will be to score the ties havil'lg old rails and tie plates so that the plates can be replaced. in proper alignment, at the proper depth, and at the desired slope if the track is banked. This operation can also be performed if new rails and plates are to be substituted for the old ones.

The truck is placed on the track and pulled along by hand or by a motor driven truck to which it may be connected. The distance between the saws of each pair is just sufficient to define the proper space between cuts or scores on the ties to receive the tie plates. The depth to which the saws cut is regulated by previously adjusting the threaded sleeves on the rods extending up from the saw shaft blocks above referred to. The inside and outside cuts may be of the same or different depths as required. VVheu the sleeves are adjusted the blocks with the saws are allowed to drop down between their guide plates until the bottom of the adjusting sleeves contact with the top of platform 27 at which time it is known that the proper depth of cut will be produced. lVhen the saws are thus disposed, the bolts, connecting the bottom of the pairs of guide plates in which the saw blocks slide. are tightened by turning on their respective adjusting arms whereby the saws are clamped in proper position.

To raise the saws, the adjusting arms are turned rcversely, loosening the lower bolts. The hand wheel is turned, winding up the cables to pull the saw blocks upwardly. lVhen in elevated position the dogs are engaged with the threads on the vertical adjusting rods to hold the saws in this position. The tension of the driving belts can be easily kept adjusted as desired, in the manner described.

Thus it will be seen that the apparatus is simple, compact and efiicient for ready operation by one or two men. When the saws are once adjusted for a definite cut, the work can proceed rapidly while at the same time the saws can be stopped and raised at any instant without losing the adjustment. After the surfaces are scored, then the rails and tie plates can be removed and seats cut in each tie by hand to the depth between the cuts or scores made by the saws. The rails and plates, either new or old, can then be put into position.

While I have described my improvement in detail and with respect to a preferred form thereof, I do not desire to be limited to such details or form, since many changes and modifications may be made and the invention embodied in other forms without departing from the spirit and scope of the invention in its broader aspects. Hence I desire to cover all modifications and forms coming within the language or scope of any one or more of the appended claims.
